JOHN H. J. HA'INES, or NEW YORK, N. Y., ASSIGNOR TO AM OF BRIDGEPORT, CONNECTICUT, A CORPORATION OF WEST VIRGINIA.

GRAPHOPHON E To all whom it may concern:

, Be it known that I, JOHN H. J. HAINES, a citizen of the United States of America, and a resident of New York city, New York, have invented a new and useful Improvement in Gra hophones, which improvement is fully set orth in the following specification.

This invention relates to' graphophones or other talkin machines employing a relay device forii creasing the volume of sound reproduced, such as setforth in the Higham platents (Nos. 678,566; 712,930; etc.) and acdonald patents (No. 796,743, etc.).

v One part of the invention is based upon my observation or discovery that, whereas heretofore the frictiompulley or drum eonstituting a part of said relay device has been driven at a comparatively high rate of speed (about sixty revolutions per minute), the same benefits may be obtained if the said friction device be driven at a comparatively low rate of speed (say about fifteen revolutions per minute). I make use of this discovery. or observation by taking power. for revolving the-friction-pulley from nearer the motor'than heretofore, b reason of which I am enabled to ap ly t e relay device to talking-machines 'aving motors of less power than heretofore believed capable of running the machine itself and also the relay device.

The invention consists further of certain features ofconstruction which permlt the relay device being ap lied to a machine not Specification of Letters Patent.

5 is a pulley fast on the mandrel i, and driven from pulley 4 by the belt T.

All the foregoing parts are as usually employed in graphophones.

8 re resents a bracket adapted to be secured upon the upper portion 9 of the casting of the gra hophone, as by a bolt 10. At the upper en of this bracket is a bearing 11 in which is mounted the shaft 12 of the relay device.

On the underside of the bed-plate 11, I provide a lug 13, having a bearing that registers with the bearing in the lug 3 and, instead of mountin the ear 3 on the studbearing as hereto ore, rovide therefor a shaft 14 which is journaler in In s 3 and 13.

15 is a sprocket-wheel fast to t 1e outer end of shaft 14, and 16 is a sprocket-chain passing around wheel 15 and the s rocket-wheel 17, which latter is fast on the s aft 12 of the.

relay-device.

The frame 40 of the speaker has a neck or bracket 41 extending from the ed e thereof at ractically right angles, and om this nee extends a ring 42 substantially parallel with the speaker 40. Ring 42 fits into the ring 43 that forms a art of the carriage, being inserted and helm therein, and detachable therefrom, in the manner well known in the ordinary Edison phonograph construction.

Referring to Fi s. 2 and 5, 18 is a member dc ending from t 1e ordinary carriage of the ta 'ing-machine, said lu being provided with one or more rollers which run along the straight edge 19, that rises from the front of the bed-plate 1. A longer bracket arm or member depending from the carriage is anti-friction devices (rollers or ball-bearings) s end of this member 25 is pivoted a somewhat gear .34 that meshes with a similar gear (not tofore by the split-sleeve 20 that encircles the feed screw.

journaled a shaft 32 carrying a gear 33 that curved so as to extend below the mandrel and engage another'straight edge at the rear of the covering of the machine (beneath the ortion 9 of the casting 9, see Fig. 3). While do not claim the use of rollers (as just explained) as novel with myself, what I beieve to be novel is the so-adjusting of the parts that the rollers upon member 18 will ear practically all the weight of the carriage and its parts (including the relay-device), instead of having this weight borne as here- The wei ht of the carrier being thus borne'by the ro lers, all friction is practically eliminated and function of the s lit-sleeve 20 is merely to guide and steady t ecarria e.

Fig. 4 s ows not only the employment of in the telescoping-journal heretofore employed for driving the relay-device, but also 21 represents the larger section of the journal, which is tubular and mounted in the bearing 11, and has the sprocket-wheel 17 fast upon its outer end. 22 is the intermediate section, also tubular, provided externally with two diametrically opposite longitudinal rooves in which engage the two extended spIines 23 projecting inwardly from the bore of member 21. 24 represents two oppositely located internal longitudinal grooves in the bore of the member 22. 25 represents the third member of the telescoping shaft, having its diameter somewhat smaller than the bore of the member 22 in which it is seated, so as to ermit member 25 to have a slight sidewise p ayf At the inner extended key 26 provided with roller-bearings and adapted to engage in the internal grooves 24. This construction not only removes any friction of those parts, but likewise any tendency of the parts to jam or The modification shown in Fig. 7 is for the purpose of applying a relay device to a machine not originally built for one. 30 re resents a plate having two lugs 31 in whic is meshes with the first intermediate gear 3 of the machine, and having at its other end a shown) mounted on a stub axle 35. Fast on the other end of this stub axle is asprocket wheel 36, which carries a sprocket chain as in Fig. 1. (The object. of the additional gear.- ing 34-, is to give the proper direction to the revolution of wheel 36). The other parts of he apparatus are as shown in Fig. 1. The plate 30 will be secured to the bed-plate of the ta-machine, as by tapping a screwceases threaded hole into the bed-plate and screwing the two together; in like manner a screwthreaded hole will be tapped into the portion 9 of the casting, and the bracket 8 screwed thereto; the relay device proper may be screwed, soldered or otherwise fastened to the carriage of the machine; and, finally,

the sprocket chain is slipped over the sprocket-wheels 36 and 17.

I have described my invention with some particularity, yet for the sake of clearness only, without intending thereby to limit myself to the precise constructions shown, since the same may be modified without departing from the spirit of my invention; for instance I may dispense with sprocket-wheels and chain and employa shaft with mitered gears. It will also be understood that parts of my invention may be used to the exclusion of other parts.

Having thus described my invention, I claim:

1. The combination with a talking-nia- .chine, of a detachable relay-device comprisadapted to be secured to the talking-machine,-

and the relay-device proper adapted to be secured to the carriage of the talking-machine and actuated through said sprocketwheels.

3.
